JOLLIE AND JOLLIE-MOLD.

SPECIFICATION forming part of Letters Patent No. 415,443, dated November 19, 1889.

Application filed March 3, 1888. Serial No. 266,112. (No model.)

To @ZZ whom it r11/ary concern/ Be it known that l, TOWNsEND C. BUDD, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio,

have invented a certain new and useful .lollie and Jollie-Mold, of which the following is a specication.

My invention has relation to improvements in thatclass oi crock-turning machines known to as joliies, in which a metallic cup-shaped head mounted on and revolved by a vertical shaft receives successively crock -molds of plaster-of-paris, which, by means of an annular shoulder, rest on the upper edge of the 15 head and revolve with it, the molds having proper internal shape to form the outside of the crock, and in which plastic clay is placed and turned to the desired thickness, when they are successively removed with the green crock inside, and placed where by drying the crock will shrink and separate from the mold. This construction an d process is objectionable because, ordinarily, a separate head is required for each size of mold, and as a day is commonly necessary to sufiiciently dry the crock to permit its removal from the mold the number of molds must equal the daily product. It is also objectionable because the crock when removed is so dry that it is difficult to attach the handles, and because the molds, being unprotected, are frequently broken.

The objects of my invention are to overcome these objections by the construction of 3 5 a jollie-head in which molds for different sizes of crooks may be used, and molds to be used therewith of such construction that they will be protected against breakage, and from which the crock will separate in a few minutes and be left in a green state suitable to receive the handles.

My invention consists in the devices illustrated in the accompanying drawings, as hereinafter described and claimed.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure 1 is vertical central sect-ion of a jolliehead; Fig. 2, an elevation of the crock, moldbottom, and port, the mold-body in vert-ical central section; Fig. 3, a set of rings toad- 5o just the head to dit'erent forms of mold.

The head A, mounted on the vertical shaft l, is substantially the same in shape as those in common use, but has on the inside two rims a a, nea-r the top and bottom, respectively, on which rest two flat rings e e', Which fit the internal diameter of the head at these points, and the openings ot' which tit the mold.

The mold consists of an outer case C of metal, usually of cast-iron, and with an orifice 6o in the bottom with sloping sides in which fits a metallic plate c, on thebottom of which are two cleats 'i l[ The inside of the case C and plate c have linings of plaster-of-paris D d, respectively, which constitute the mold for the outside of the crock, the edges of the lining d being' sloped at substantially the same angle as the edges of the plate @,With the top of the same size as the interior of the lining D. There is thus formed a complete mold 7o for the outside of the crock, with a bottom that can be forced up through the body, and the parts of which are prevent-ed trom breaking by their metallic supports.

In operation, the proper rings e e having been placed in the head, the mold is fitted therein and a crock of plastic clay turned in it in the usual manner, Near the jollie is a number of fixed posts with fiat heads, one whereof F is shown in Fig. 2. The crock 8o having been turned, the mold is removed from the head and placed on the post F and the operation repeated with another mold. In a short time, varying from one-half to an hour, the crock dries and shrinks sufficiently to permit it to separate from the body of the mold, which falls straight down around the post, leaving the pot and bottom (l on the post, as shown in Fig. 2, whence they are removed to any suitable place, the cleats 'it' 9o supporting the plate c sufficiently to permit the hands to pass under it. By this arrangement the number of molds required for any given number of crocksis materially lessened, as the same molds can be used several times each day, separate bottoms for each crock only being needed, and the crock is released in a green state suitable to receive handles,

While by the use ofdifferent rings e e difierent sizes of molds can be used in the same head.

I claim as my inventionl. A jollie having an outer metallic body with an openingin the base having upward outwardly-sloping edges, and lined with plaster-of-paris to determine the shape of the molded article, and having a loose metallic plate set in the opening in its base, removable upward from its seat, substantially as shown and described, and for the purpose specified.
